About the ChemStation Software
allow rapid access to instrument parameters and an animated graphical
overview of the status of each analysis as it proceeds. The schematic
instrument diagram may be turned off if it is not required, to save memory
and other Windows resources.
The Data Analysis view extends the standard toolbar to specific data analysis
modes including integration, calibration, reporting, annotation, signal
comparison and additional specialized modes if the modules are installed.
Each of these separate data analysis modes are supported with a
mode-specific toolset.
The Report Designer view allows the user to graphically define the layout of a
specific report style in a graphical object orientated fashion. It also uses a set
of toolbars specific to this task.
Data Acquisition
The status of the instrument is continually monitored and updated on the
display, along with the elapsed run time of the analysis both when the
software is a visible window and when it is iconized. The transactions that
occur during the analysis, including any errors and the instrument conditions
at the start and the end of the analysis, are recorded in the system’s logbook,
an extract of which is stored with every data file.
The instrument conditions, such as flow, temperature, pressure and solvent
composition for liquid chromatographs may be recorded and stored with each
data file. These instrument parameters can be displayed and plotted to testify
to the quality of each analysis. The exact nature of the parameters recorded
depends both on the technique and the capabilities of the configured
instrument.
One or more display windows may be used to monitor the data being acquired
by the instrument in real time. The data are displayed in real measurement
units such as mAU, Volts, degrees or bar. The windows may each show multiple
overlaid chromatographic/electropherographic signals or instrument
parameters, such as pressure. The display default settings may be adjusted
and are remembered by the system so users can set their own preferred
settings as the instrument default. The window has zoom capability and the
cursor may be used to display a specific signal’s response at any point in time.
